How to create an angular 2 build folder when using systemjs.config.js

My app works fine locally. I need help with my gulp file so I can grab the node modules required and move them to the dist folder ready for deployment.

This is my gulp folder:

const gulp = require('gulp');
const ts = require('gulp-typescript');
const uglify = require('gulp-uglify');
const concat = require('gulp-concat');
var htmlreplace = require('gulp-html-replace');
var addsrc = require('gulp-add-src');
var sass = require('gulp-sass');    
var inject = require('gulp-inject');
var del = require('delete');
var minifyCss = require('gulp-minify-css');    
var CacheBuster = require('gulp-cachebust');
var cachebust = new CacheBuster();

gulp.task('app-bundle', function () {
  var tsProject = ts.createProject('tsconfig.json', {
      typescript: require('typescript'),
      outFile: 'app.js'
  });

  var tsResult = gulp.src([
    'node_modules/angular2/typings/browser.d.ts',
    'typings/main/ambient/firebase/firebase.d.ts',
    'app/**/*.ts'
  ])
    .pipe(ts(tsProject));

  return tsResult.js.pipe(addsrc.append('config-prod.js'))
                    .pipe(concat('app.min.js'))
                    .pipe(uglify())
                    .pipe(gulp.dest('./dist'));
});

gulp.task('vendor-bundle', function() {
    gulp.src([
            'node_modules/es6-shim/es6-shim.min.js',
            'node_modules/systemjs/dist/system-polyfills.js',
            'node_modules/angular2/bundles/angular2-polyfills.js',
            'node_modules/systemjs/dist/system.src.js',
            'node_modules/rxjs/bundles/Rx.js',
            'node_modules/angular2/bundles/angular2.dev.js',
            'node_modules/angular2/bundles/http.dev.js'
        ])
        .pipe(concat('vendors.min.js'))
        .pipe(uglify())
        .pipe(gulp.dest('./dist'));
});

gulp.task('add-styles', function() {
    gulp.src([
      'css/animate.css',
      'css/bootstraptheme.css',
      'sass/styles.scss'
    ])    
    .pipe(sass().on('error', sass.logError))
    .pipe(concat('styles.min.css'))
    .pipe(minifyCss({compatibility: 'ie8'}))
    .pipe(cachebust.resources())
    .pipe(gulp.dest('dist/'))   
});

gulp.task('add-images', function() {
    gulp.src([
      'images/*.png'
    ])    
    .pipe(gulp.dest('dist/images'))     
});

gulp.task('add-bits', function() {
    gulp.src([
      'favicon*.*',
      'sitemap.xml',
      'robots.txt',
      'firebase.json'
    ])    
    .pipe(gulp.dest('dist/'))     
});

gulp.task('html-replace',[ 'app-bundle', 'vendor-bundle', 'add-styles', 'add-images', 'add-bits'], function() {
  gulp.src('index.html')
    .pipe(htmlreplace({
        'vendor': 'vendors.min.js',
        'app': 'app.min.js'
    }))
    .pipe(gulp.dest('dist'));
});

This is a screen grab of my current dist folder ready for deployment live. But is missing the node modules required:

This is my config file:

(function(global) {

  // map tells the System loader where to look for things
  var map = {
    'app':                        'app',
    'rxjs':                       'node_modules/rxjs',
    'angular2-in-memory-web-api': 'node_modules/angular2-in-memory-web-api',
    '@angular':                   'node_modules/@angular'
  };

  // packages tells the System loader how to load when no filename and/or no extension
  var packages = {
    'app':                        { main: 'boot.js',  defaultExtension: 'js' },
    'rxjs':                       { defaultExtension: 'js' },
    'angular2-in-memory-web-api': { defaultExtension: 'js' },
    'angular2-google-maps': { defaultExtension: 'js' }
  };

  var packageNames = [
    '@angular/common',
    '@angular/compiler',
    '@angular/core',
    '@angular/http',
    '@angular/platform-browser',
    '@angular/platform-browser-dynamic',
    '@angular/router',
    '@angular/router-deprecated',
    '@angular/testing',
    '@angular/upgrade',
  ];

  // add package entries for angular packages in the form '@angular/common': { main: 'index.js', defaultExtension: 'js' }
  packageNames.forEach(function(pkgName) {
    packages[pkgName] = { main: 'index.js', defaultExtension: 'js' };
  });

  var config = {
    map: map,
    packages: packages
  }

  // filterSystemConfig - index.html's chance to modify config before we register it.
  if (global.filterSystemConfig) { global.filterSystemConfig(config); }

  System.config(config);

})(this);

These are the node modules I think im missing and need to add to dist folder and link to dist folders index.html

  var packageNames = [
    '@angular/common',
    '@angular/compiler',
    '@angular/core',
    '@angular/http',
    '@angular/platform-browser',
    '@angular/platform-browser-dynamic',
    '@angular/router',
    '@angular/router-deprecated',
    '@angular/testing',
    '@angular/upgrade',
  ];

Try this:

//in the gulpfile.js
gulp.task("angular", () => {
    return gulp.src([ '@angular/**','rxjs/**']).pipe(gulp.dest("./dist"));    
});

// in the config.js
var map = {
   'app':                        'dist', //I guess that the problem was here
   'rxjs':                       'dist/rxjs',
   'angular2-in-memory-web-api': 'dist/angular2-in-memory-web-api',
   '@angular':                   'dist/@angular'
};

Answer 2

Your gulp-task vendor-bundle suggests that you want a bundle of the dependencies used in your app. If you can use system-js-builder, it'll be very easy.

• It will be much smaller than the whole bundle of angular or rxjs

Just run this

---

It'll include angular and rxjs dependencies

var gulp = require('gulp'),
  Builder = require('systemjs-builder');


gulp.task('bundle-dependencies', function() {
  // optional constructor options
  // sets the baseURL and loads the configuration file
  var builder = new Builder('', 'config.js'); // config.js is the name of systemjs config file

  return builder
    .bundle('app/boot.js - [app/**/*.js]', 'path/to/put/dependencies.bundle.js', { minify: true})
    .then(function() {
      console.log('Build complete');
    })
    .catch(function(err) {
      console.log('Build error');
      console.log(err);
    });
});

for a complete guide see my another answer Compile Angular 2 node_modules files into one file.

Note: path/to/put/ is the path where you want to export the bundle.

---

If you want files of the dependencies, I'm sorry. But I'd suggest to create a bundle intead of having seperate files.
